Patent No. 295,165, dated. March 18, 1884.

(No model.)

To all whom, it may concern Be it known that we, WILLIAM HALL and JOHNMIDGLEY, subjects of the Queen of Great Britain, residing in Pawtucket,in the county of Providence and State of Rhode Island, have jointlyinvented a new and useful Improve ment in Machines for Gombing FibrousMaterial; and we do hereby declare that the following specification,taken in connection with the accompanying drawings, forming a part ofthe same, isa full, clear, and exact description thereof.

Our invention consists in the means employed for combining the twoslivers which are produced on opposite sides of the machine, and tomeans for preventing any portion of such slivers from winding about therolls which deliver said slivers, whereby the machine is simplified inconstruction and rendered more perfect in action, as will hereinafterappear. I

Referring to the drawings, Figure l represents in plan a portion of amachine embodying the improvement as applied to oncot' the well-knownforms of combing-machines.- Fig. 2 shows in plan a portion of acombing-inachine in general use. Fig. 3 represents an elevationandpartial section of the improved machine, showing the means forrotating the combs, rolls, 8:0.

The machine in common use, a portion of which is shown at Fig. 2,employs a large annular revolving comb, A, two small annular revolvingcombs, B B, two pairs of fluted rolls, 0 a and O c, which remove thematerial from the combs B B, respectively, two pairs of rolls, D D and DD, which draw material from the comb A, aprons E Eand F F, which deliverthe slivers from the rolls D D and D D to the rolls (3 c and G 0',respectively, two revolving trunipetsgG G, for receiving and twistingthe slivers gg, respectively, two pairs oi'condcnsing-rolls, I-I H, arevolving guidetrumpet, J, located between said pairs oi rolls, and aduct or conveyor, K, for delivering the product from the machine, Themeans by which the combs, rolls, 850., are revolved are shown in Fig. 3.

The machine is provided with a drivingshaft, M, bearing beveled gears inm, which meshwith beveled gears m 127, on shafts M M*, respectively. Bymeans oftrains of gears 1, 2, 3, 4 and 5. (5. 7, 8 the shafts M Mrespectively revolve shafts N N, each of which is provided which isshown. The'gears-n mesh with an A, by means of which said comb isrevolved. The comb B is rotated by gears 9, 10, 11, the former being onthe shaft N, and the latter meshing with the gear b on said comb. Thecomb Bis similarly revolved from the shaft N, the gear upon the upperend of said shaft meshing with the gear b on said comb. One of the rollsD is driven from the-shaft M by suitable gearing connecting with thegear cl on the shaft (1. upon which shaft the said roll is mounted. Thefellow roll D is revolved by friction. One of the rolls D is driven fromthe shaft M by suitable gearing connecting with the gear (1 on the shaft(1, upon which shaft the said roll is mounted. The fellow roll D isrevolved by friction. The rolls G and O are driven from the shafts M andM respectively, by suitable gearing connectim with the gears r and r onthe shafts R and It, upon which the rolls 0' and O are respectivelymounted. The fellow rolls a and c are revolved by friction.

The combing-machine above referred to as in common and general use isknown under the name of the Noble comb, and asawhole is a very complexmachine. Fig. .3 of the drawings, however, sufficiently exhibits to anyperson skilled in the construction of this class of machines the meansby which the several combs and drawing-0d" or delivery rolls areactuated, in order to render intelligible the improvement which we havemade.

. \Ve have found that in the use of combingmachines of formerconstruction-such as are illustrated at Fig. 2--p01tions .of the sliversare liable to wind about the rolls 0 G to such an extent as to bendand'oftcntimcs to break the teeth of the combs B B, to which said rollsare closely adjacent, thereby greatly damaging the machine.

The object of our improvement is to siminternal gear, P, attached to themain comb at its upper end with a gear, a, only one of plify theconstruction of the machine, in order I less attention on the part ofthe operative,

to more effectually prevent the slivers from winding about the rolls 0 Oand injuring the combs. To these ends we dispense with the trumpets G Gand the mechanism used for revolving the same. and, as shown in Fig. 1,employ an apron, L, which passes around the rolls 0 and O, and conveysthe sliver g from the rolls 0 c to the rolls O0, in order that saidsliver may be combined with the sliver g, and both slivers be condensedby the rolls 0 0, thereby enabling the condensing-rolls H, Fig. 2, andmeans for driving the same, to be dispensed with. The apron L alsoperforms an other valuable office, in that,by passing around the rolls 0andO, it prevents any portion of the slivers from winding about saidrolls and causing damage to the teeth of the combs B B. Thus. it will beseen, from an inspection of Fig. 1, that the sliver delivered by therolls D, when it reaches the belt L, combines with the sliver from thecomb B, and as the endless belt L travels in the direction indicated bythe arrow and covers the roll 0', it is impossible for any portion ofthe sliver to wrap around the roll 0 and become entangled with the teethof the comb 13, and the same protection against entanglement with theteeth of the comb B is provided at the roll G. Preferably the apron F isextended. as shown in Fig. 1, as an assistant in guiding the sliveralthough such extension is not essential. The combined slivers havingbeen condensed by the rollsG a into a single sliver, g, as shown in Fig.1, such sliver passes directly to the revolving trumpet J, which isconstructed to perform the twisting operation. From the trumpet J thesliver is delivered from the machine by-the usual mechanism.

From the foregoing description it will be seen that the characteristicfeature of our improvement is combining the delivery-rolls G and O bymeans of an endless conveyer-belt, L, whereby the slivers, which are theproducts of the action of the combs, are prevented from wrapping aroundthe rolls 0 O and becoming entangled with the teeth of the combs B B.Incidentally, the rolls 0 c and G 0 can be made of smaller diameter thanthe rolls formerly used, and be set closer to their respective combs BB. The whole apparatus is simplified in construction, and requires farand the resulting sliver delivered as the final product is more solid,and therefore less liable to break down, for the reason that itscomponents have traveled through a better protectedand less broken paththan they were obliged to travel in the old Noble machine.

We are aware of the improvement in this class of machines described inEnglish Patent No. 2,529 of 1877. Our improvement is distinguishablefrom that described in said patent in the circumstance that the rolls 0and G of the two sets of drawingoff or delivery rolls,

appropriate to the two small revolving combs, are directly connectedwith each other by means of an endless traveling apron or conveyer, andto prevent the liability ofthe slivers becoming wrapped around therolls,only this one endless belt is required, whereas in the machinedescribed in said English patent these two sets of rolls are not soconnected, and the employment of two endless belts and suitableguide-pulleys for the same is necessary to protect the two combs.

What we claim as our invention, and desire to secure by Le ters Patent,is-

1. The combination, substantially as hereinbet'ore set forth, of therevolving cou'ibing-cylinders B B, delivery-rolls C c and G c,appropria'te thereto, and an endless traveling apron or conveyorarranged to embrace the rolls 0 and Got the two sets of delivery-rollspertaining to the combing-cylinders, respectively, substantially asdescribed.

2. The combination, substantially as hereinbefore set forth, of therevolving combing-cylinder A, the revolving combing-cylinders B B,delivery-rolls G c and O c, appropriate, respectively, to the lattercombs, means, substantially as described, for conveying the combedslivers from the comb A to the said rolls, and an endless travelingapron or conveyer directly connecting the rolls G and O of the two setsof delivery-rolls, whereby the combed product is conducted so as to beunited in a single sliver, as set forth.
